The profile is the storefront and the website is the follow-up
Most restaurant discovery resolves in the map results, where the decision is often made without anybody visiting a website.
Somebody looking for a place to eat sees a photograph, a rating, a price indicator, the hours and how far away it is. That is frequently enough to decide.
Which means the profile deserves the attention normally given to a website. Current hours including holidays, accurate categories, real photographs of the actual food, and answers to the questions people ask there.
Hours are the most common failure and the most damaging. Somebody who arrives at a closed restaurant does not simply go elsewhere; they leave a review about it.
Photographs on the profile matter more than photographs on the site, because far more people see them. They also need refreshing, since a profile showing dishes you stopped serving is actively misleading.
The website's job is what the profile cannot do: the full menu, the story, private events, catering and anything requiring more than a glance.
